It’s more expensive to ship across the oceans and requires a whole set of other infrastructure.
It only needs two ports and two docks. One of each at each end of the shipping route.
It’s exceedingly more easy to ship across land borders and to try and say my point isn’t valid like this is laughable.
Do you really think building and maintaining thousands of miles of roads and rails is cheaper than a few ports?
A hotdog by definition always contains a boiled sausage stuffed inside a bun or something similar. A currywurst isn’t a hotdog. It comes with fries and no bun Also that Germany variant in the pic isn’t one. It’s just the plain old delicious Bratwurst and Sauerkraut.
The standard hotdog you can find in Germany consists of a bun and sausage with ketchup, mustard, crispy onions, pickles and sometimes cole slaw.
